HOdlcoin

HOdlcoin is just like Bitcoin, but it pays interest on every balance. This is to recognize the importance of HODLers and properly reward HODLing.

Very high interest rates (4000%+ APR) are paid in the first few months to attract early adopters to the project.

Proof of Work

1GB AES Pattern Search POW. Pattern Search involves filling up RAM with pseudo-random data, and then conducting a search for the start location of an AES encrypted data pattern in that data. Pattern Search is an evolution of the ProtoShares Momentum PoW, first used in MemoryCoin and later modified for use in CryptoNight(Monero,Bytecoin), Ethash(Ethereum). CPU/GPU friendly.

Interest is paid on regular balances (outputs), on every block, for a period of up to 30 days (561x30 blocks). The rate is 0.0000002384185791015625% (1/2^22). It's compounded every block, so the rate is approximately 5% APR. However, remember there is a maximum of 30 days, so to get that APR, you'd need to log in each month and shuffle the HODL to a new address.

2. Bonus Interest Rates

To encourage early adoption, astronomical rates of interest are paid in the early months. The max rate is 0.0000152587890625 (1/2^16). Compounded, the rate is 2174%. It's reduced every block by a multiplier - calculated like this =((409530-X)/409530)^4 (X is the block where the balance is recorded as an output).

To calculate your bonus rate, you can use this formula.

Principal + (Standard Interest + (Bonus Interest * Bonus Multiplier)

Bonus rates

Day 0 ~ 2174%

Day 30 ~ 1881%

Day 60 ~ 1543%

Day 90 ~ 1317%

Day 660 ~ 0.230% APR

Day 690 ~ 0.029% APR

Day 730 ~ no bonus

3. Term Deposit Bonus

If you lock an amount of HODL as a term deposit, you can also get a bonus on the interest. The longer the deposit, the bigger bonus. The bonus is just a multiplier of the interest, so if you locked up 100 HODL for 1 year, you'd expect a return of 5 HODL. The term deposit bonus for 1 year is about 100% - so at the end of the term you'd have 110 HODL (Capital 100 + Interest 5 + Term Deposit Bonus 5). See the chart for the multipliers, or use this formula - =(1-((409530-X)/409530)^6)*100 (X is the number of blocks to lock for, min 2 days, max 1 year)
